According to the fiscal, The net collections of direct tax stood at ₹16.61 crore in the financial year 2023. Even after such huge tax payments in our country most of the taxpayers aren't aware of rounding off tax under GST. 

In regular Business situations. Taxpayers often encounter a scenario where the amount of tax they need to pay ends up being in decimals, like a fraction of a rupee. Which then raises an important question, "How much tax should I actually pay?". To make this tax calculation easier and avoid confusion, section 170 of the CGST Act provides rules for rounding off tax. In the past, businesses used different methods like rounding up or down, but it's essential to know the right way to round off taxes under the GST law. Let's delve deep into it in this article.

Methods of Rounding Off Tax

In the realm of GST, three principal methods of rounding off tax liabilities have historically been employed by businesses:

Upward Rounding Off

This method entails rounding the value of paise (decimal fraction of a rupee) upwards to the nearest whole rupee. For instance, if the calculated tax liability amounts to ₹10.40, it is rounded up to ₹11.

Downward Rounding Off

In this approach, the value of paise is rounded downwards to the nearest whole rupee. For example, if the tax liability is ₹10.70, it is rounded down to ₹10.

Normal Rounding Off

The most intricate method, normal rounding off, takes into consideration the value of paise and the digit after it. If the value of paise is greater than or equal to 50, it's rounded upwards to the nearest rupee. Conversely, if the paise value is less than 50, it's rounded downward to the nearest rupee.

The Correct Method under GST

Under the GST regime, the correct method of rounding off tax liabilities is the normal rounding off method, as mandated by Section 170 of the CGST Act. This decision was taken to facilitate simpler and more transparent tax calculations for businesses. Whether it's tax, interest, penalty, refund, or any other payable amount, all should be rounded off to the nearest rupee using the normal rounding off method.

Rounding Off for Multiple Invoices

When dealing with multiple invoices, it is essential to determine whether rounding off should be applied on an individual invoice basis or as a consolidated approach. The answer lies in the fundamental principle that tax liability should be assessed individually for each invoice. Additionally, rounding off should be performed separately for components like the Central GST (CGST), State GST (SGST), Integrated GST (IGST), and more. This granular approach ensures accuracy and adherence to the GST regulations.


In conclusion, navigating the intricacies of tax calculations can often be a perplexing challenge for businesses, especially when dealing with decimal values. The advent of the GST introduced a streamlined approach to tax assessment and collection. One such significant aspect is the rounding off of tax liabilities. So, by embracing the normal rounding off method and applying it to individual invoices and tax components, businesses can ensure accurate and transparent tax assessments.
